Product Description

The Drillco 1000EC series reduced-shank drill bit is made from cobalt steel with a bronze finish and has a 135-degree split point for use on tough, high-tensile strength metals. The reduced shank drill bit, also called a Silver and Deming drill bit, has a shank that is smaller in diameter than its shaft, permitting drilling with a 1/2" drill chuck. Cobalt steel provides extended tool life compared to high-speed steel drill bits, and maintains the tool's toughness and hardness in high drilling temperatures. The bronze finish lubricates the drill bit and provides wear resistance. The self-centering 135-degree split point penetrates hard material without a pilot hole and produces smaller chips that reduce clogging compared to a 118-degree point. The round shank with flats ground onto three sides reduces slippage of the bit when used in drill chucks. The drill bit conforms to American National Standards Institute (ANSI) specifications.

Drill bits are cutting tools used to make holes in a range of materials using machines such as handheld portable drills, machining centers, and lathes. Drill bits come in a variety of lengths and types, the most common of which is the twist drill bit. The round, twisted shaft of the twist drill bit typically has two cutting edges and flutes. The helical twist of the flutes brings chips up and away from the cutting edges and allows for coolant to reach the cutting edges. Jobber length twist drill bits, the most common length of twist drill bit, offer a good compromise of length and reach for the widest range of materials and applications. Mechanic's length twist drill bits (also called maintenance length) are a little shorter than jobber length and less prone to deflection when drilling. Short length twist drill bits (also called stub or screw-machine length) are the shortest and stiffest twist drill bits, helping to reduce the chance of deflection or breakage when drilling. Reduced shank twist drill bits (also called Silver and Deming drill bits) have a shank that is smaller in diameter than its shaft, permitting drilling machines with a 1/4", 1/2", or 3/4" drill chuck to create large holes. Long length twist drill bits (also called taper length) are a little longer than jobber length, allowing for deeper holes and longer reach. Extra-long length twist drill bits (also called extension) are longer than long length twist drill bits for greater reach or for drilling deeper holes.

Drillco manufactures cutting tools such as drill bits, reamers, taps, dies, annular cutters, end mills, and burs. The company, founded in 1978, is headquartered in Baton Rouge, LA.
